Risk levelLow

0–100, higher is better. How it is calculated

Sudlows is a UK-based international specialist in data centres and critical infrastructure services, offering design, build, audit, testing, maintenance, and consultancy. The company holds multiple certifications and serves a broad enterprise clientele globally, positioning itself as a leading provider in its sector. The website reflects a mature digital presence with professional design, clear navigation, and comprehensive service descriptions. Technically, the site uses WordPress with modern JavaScript libraries and analytics tools, ensuring good performance and user experience. Security posture is solid with HTTPS and GDPR compliance, though improvements in security headers and incident response transparency are recommended. The absence of WHOIS data is a notable concern but does not outweigh the strong business indicators present on the site.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

2 findings rated critical or high. Fix these first.

  1. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Sudlows operates in the energy and technology sectors, focusing on mission-critical infrastructure projects. Its business model is B2B, targeting enterprises requiring advanced data centre and infrastructure solutions. The company demonstrates competitive advantages through multi-award recognition, certifications, and a global footprint. Revenue streams likely derive from consultancy, design-build contracts, maintenance services, and facilities management. The partnership ecosystem includes notable clients and a presence in multiple regions. Growth indicators include recent leadership promotions and award wins. Strategic observations suggest a focus on sustainability and innovation within critical infrastructure.

Security posture

The website exhibits a mature security posture with enforced HTTPS, GDPR-compliant cookie consent, and CAPTCHA protection on forms. However, the lack of visible HTTP security headers such as CSP, HSTS, and X-Frame-Options represents an area for enhancement. No vulnerabilities or exposed sensitive data were detected in the HTML content. Incident response and vulnerability disclosure information are absent, which could be improved to bolster security culture and readiness. Overall, the site aligns well with industry best practices but should address these gaps to strengthen its security maturity.

Recommendations

  1. Implement comprehensive HTTP security headers including Content Security Policy, HSTS, and X-Frame-Options.
  2. Publish an incident response policy and vulnerability disclosure program to improve transparency and readiness.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance server-side validation and rate limiting on forms to prevent abuse.
  5. Maintain domain registration visibility and ensure WHOIS data is accurate and accessible to improve trust.

  4. Comprehensive privacy and cookie policies with GDPR compliance.
  5. Use of modern web technologies and analytics tools.

Technical notes

Notes

The website is built on WordPress with a modern tech stack including jQuery, Owl Carousel, Gravity Forms, Google Tag Manager, Google Analytics, and Hotjar. Performance is moderate with good mobile optimization and accessibility features. The site uses Cloudflare Turnstile CAPTCHA for bot protection. There is no explicit hosting provider identified. Technical debt appears low, but the absence of security headers and incomplete WHOIS data represent risks. Opportunities exist to modernize security configurations and improve domain registration transparency to support business continuity and trust.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
